Global Climate Change Essay Example for Free

Global Climate Change EssayClimate change pertains to the deviation in the global temperature through a course of time. It portrays the alterations in the standard condition of the asynchronous transfer mode for a situation period of time, extending from years to centuries. It has been firm that temper change is the result of various courses, both internal and outer with respect to the planet. The phrase modality change has lately been applied to issues of environmental planning strategies and approximately 90 95% of this variation has been attributed to human activities. This human derived concept has then been categorized as anthropogenic climate change and the media has then presented this phenomenon as global warming. Other non-governmental agencies have also pargonntred to this occurrence as climate variability. In this paper, climate change and global warming will be used interchangeably to refer to the make up in temperature of the Earths atmosphere. DETAILS OF CL IMATE CHANGE Climate change pertains to the increase in temperature of the atmosphere based on the entrapment of gases that are emitted from activities on the surface of the earth.The increase in temperature is a direct result of the glasshouse effect, which involves heat that originated from the sun, which is entrapped within the atmosphere due to several factors. Scientists have determined that the atmospheres temperature has increased since the industrial revolution, which has maximized the use of chemicals in manufacturing various kinds of materials in industry. There are four principal gases that have been identified to be primarily liable for the onset of global warming. ampere-second dioxide (CO2) is accountable for approximately half of the glasshouse gases in the atmosphere (Pearson and Palmer, 2000). This gas is a by-product of fogey fuel combustion, which involves burning of coal, natural gas and oil. It is also generated from deforestation activities, which have incr eased for expansion of industrialisation areas. Trees utilize carbon dioxide in their photosynthetic reactions, but it there are fewer trees in the environment, less(prenominal) CO2 is removed from the atmosphere, leaving the environment with excess amounts of CO2.Another gas that has been determined to be responsible for global warming is chlorofluorocarbons (CFCs), which are the primary constituent of p break downics and aerosols, as well as refrigerants in pedigree conditioners. Chlorofluorocarbons make up approximately 25% of the greenhouse gases in the atmosphere. Thirdly, methane gas (CH4), which comprises approximately 12% of the greenhouse gases, is also accountable for global warming. Methane gas is released during the decay of organic matter, as well as in the stomachs of cattle, sheep and termites, yet, most of the gas is currently generated by industrial companies.Lastly, nitrous oxide (N2O) is responsible for approximately 6% of the greenhouse gases. It is a by-product of industries, as well as nitrogen fertilizers, volcanic eruptions and livestock manure. HISTORICAL account statement OF CLIMATE CHANGE The process of global warming through the greenhouse effect was historically depict in 1824 by Joseph Fourier. The details of the greenhouse effect were eventually examined in 1896 by Svante Arrhenius. These investigations resulted in the inclination of the mechanisms behind the increase in temperature through the absorption and release of infrared radiation by gases that existed in the atmosphere.The radiation in turn increased the temperature of the Earths surface and its adjacent surrounding atmosphere. interrogation has shown that the greenhouse effect is a natural occurrence that is influenced by gases that are naturally present in the atmosphere. It has actually been postulated that the initial greenhouse effect of the Earth is beneficial for biological species to survive because it warms the Earths surface to a temperature of approximate ly 33oC.Should the greenhouse effect be absent, any biological species would not be able to survive through the harsh cold temperature of the Earth. However, the accumulated effect of human activity during the last few centuries has affected the greenhouse phenomenon, resulting in a significant increase in the concentration of grumpy gases. This increase in concentration subsequently influenced the atmospherical temperature to increase. The first greenhouse gas that was identified is water vapor. This gas comprises around 36 to 70% of the total greenhouse effect.Another greenhouse gas that was know is carbon dioxide which makes up 9 to 26% of the total atmospheric complex. Approximately 4 to 9% of the atmosphere is also composed of methane gas, while around 4 to 9% is made up of ozone. Historical atmospheric analysis has shown that the amount of these gases has increase by almost 75% since the 18th century industrial era. geologic research has indicated that the amount of carbon dioxide in the atmosphere has reached its highest concentration in the last 20 one thousand thousand years of the Earths existence.
